That's correct.  VPATH is global.

Perhaps you should take a look at the vpath directive.

For example, suppose that I want a specific VPATH search path for a 
specific target I can do the following:

    .PHONY: all
    all: foo.bar ; @echo $@ $<

    vpath foo.bar src/

    foo.bar: ; @echo Making $@

If there's a foo.bar in the src/ directory then the vpath directive will 
cause it to be used and you'll see the following output:

    all src/foo.bar
